PERMUTATlON-PADLOCK.

Specification of Letters Patent.

Patented April 30, 1907.

Application filed June 6,1906. Serial No. 320,4:23.

have invented certain new and useful Improvements in Permutation- Padlocks, of which the following is a specification.

My invention relates to improvements in permutation padlocks and has for its object to produce a padlock of the type set forth,

which shall be simple, ellicient and strong and one which can be readily operated, and the combinations (of whicha great number may be used), changed at will in a simple manner I 5 without dismembering the component parts.

To these ends my invention consists in certain novel features of construction, arrangement and. combination of parts as will be hereinafter fully described and pointed out in the claims, reference being had to the accompanying drawings, in which Figure 1 is a perspective view of a lock embodying my improvements. Fig. 2 is a ver tical section of same,.showing the shackle Fig. 3 is a similar section with the shackle released or unlocked. Fig. i is a horizontal section 011 line 4et of Fig. 2. Fig. 5 is a similar view on line 55 of Fig. 3. Fig. 6 is a side view showing locking sleeves Fig. 7 is a side view of the body portion with shackle and locking parts re moved. Fig. 8 is a top view of same. Fig. 9 is a perspective view of the plunger removed. Fig. 10 is a similar view of the Fig. 11 is a perspective view of one of the locking sleeves.

In carrying out my invention I use a casting or body portion A of suitable size and shape having the vertical passage A bored 4 through one end to receive the long leg of shackle B said bore is internally threaded near its lower end to receive the threaded lower end B ofthe shackle B, as shown in Figs. 2 and 3. The opposite end of the body portion is also provided with a vertical bore A somewhat larger than the bore A, and a suitable number of horizontal slots A are cut into the body portion intersecting the bore A and extending toward the vertical center 5 of the body portion, as indicated in Fig. 7.

The shackle B which consists of the long leg B and the short leg B is provided in its longer leg with the horizontal sockets l) within which are placed coiled springs b which bear against small dowel pins 5 these small sockets corresponding In number to the cutout portions in the other side of the body; the

longer leg B is also provided with the angular recess 6, just above the upper horizontal socket 1), within which the rear end or nose 0 of a latch C plays, said latch being pivoted within a vertical slot a at a, as shown in Fig. 3, and having the nose 0 at its other end.

WVithin. the hole A of the body portion, said hole or opening extending not entirely through the body vertically, is placed a coil spring D, and over this a plug D which is provided with a vertical socket (Z in its center within which the spring D is seated; said plug is also provided with a horizontal annular flange (6 at its lower end upon which rests the lower end of the plunger E which has a central vertical opening a in its lower portion, said opening 'litting over the plug D. The plunger E is provided with an enlarged head E in the center of which is a verticalsocket e, and a slot 6 extending from said central socket to the outer edge of the head E; the slot cf is of less depth than central socket c and is designed to receive one end of the latch (l hcreinbelore referred to.

The inner vertical wall of the bore or hole A is provided with the notch or V shaped recess a to permit the passage into said bore .of the sleeves F, each sleeve having a V- shaped lug or projection fnear its upper end, said sleeves with the rings G forming the tumblers of the locks; said rings G are provided with a series of internal notches 9 any one of which will lit over the lug or projection f of sleeve F according to the combination decided on, and said rings G are also provided with a circumferential series of similar notches g around their outer edge.

Extending from each of the slots A inwardly are the horizontal passages I, extending from said slots to the bore A, and in which are placed the pins i, one end of which is Hat and the other i pointed or sharpened. These pins are intended. to bear at their flattened ends against the dowels b and their pointed ends to engage the V-shaped notches g .in the periphery of the outer member G of the tumblers of the look when the padlock is in its locked condition.

, In Fig. 2 the parts of the lock are shown in their normal locked. position; that is, the plunger E carried 011 the plug D in turn carery, one letter being arranged between every two notches, the lug f on the sleeves being placed in one of the internal notches g of rings G.

In the position of parts shown in Fig. 2, the dowels 72 press lightly against the ends of pins '21, forcing their pointed or sharpened ends i into the slots A and against the outer rings G of the tumblers, said sharpened ends jumping into the notches g on the periphery of rings G but permitting them to be freely turned.

The short leg B of the shackle has at its end the downwardly projecting pin B which when the padlock is in its locked condition fits into the socket e in the plunger E, and side movement of the shackle is thereby prevented. The upper side faces of the plungerE are rounded ofi or beveled as shown at E to permit the pin B at end of shackle to ride easily up same when looking the same.

The rings G may be designated as the indi cator rings, and the sleeves F, as locksleeves; if they are now combined as desired to un lock the padlock, the lug f on the sleeve which has been previously set in one of the internal notches g of the ring Gr must be brought into vertical alinement with the notch a in the inner wall of the bore A each indicator ring must be so turned that the lug of its sleeve is in vertical alinement with each and all of the lugs below or above it. hen the tumblers have been so turned as to accomplish this result, the plunger E may be pushed down releasing the pin 13 which will permit the short leg B of the shackle B to be swung to one side; at the same time, the long leg B of the shackle being threaded at its lower end into the body of the lock moves vertically as the leg is swung, and the heel c of the pivoted latch C is carried upwardly by the shape of the angular slot 6 and forces the nose 0 of the latch G into the slot 6 in the head of plunger E; at the same time the solid portion of leg B of the shackle is brought around and bears against the flat ends of the pins & holding the pointed or sharpened ends i of same into rigid engagement with the notched rings G, and preventing turning of the same while the shackle is open.

To lock the padlock again the short leg B is swung around again, the long leg moving downwardly during such swing until the spring pressed dowels b are opposite the flat ends of the pins i; this movement of the shackle carries the heel c of the latchC downwardly and consequently moves the nose 0 upwardly permitting the plunger to move up again; the pin 13 strikes against the rounded or beveled top side faces of the plunger, and forces it down until the pin B is immediately over the socket e when the plunger and the plug D will be moved up by the spring D and lock the shackle, the locking sleeves F being carried by the plunger in its up and down movements.

There will be, of course, some mark on the outer face of the body portion adjacent to the tumblers by which it can be known when the parts are in correct position for unlocking, and such a means may be a mark as x shown in Fig. 7 so that when the letters forming the combination are in alinement with this the padlock can be opened.

The combination can be readily and quickly changed by holding down the plunger when the shackle is in locked position turning the indicator rings G to the desired letters, and then releasing the plunger, and the locking sleeves F being carried by said plunger; the lugs thereon will be seated in other notches in the inner face of the rings G.

I claim 1.
